[Debian] [SSH] X-Forwarding als root

[Pascal Tilgner <pascal@tilchna.de>]

Hallo Liste!

Ich würde gerne X Programme als root ausführen, aber es passiert
immer folgendes:

pascal@debian:~ $ ssh -f root@localhost gcombust
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server

Gtk-WARNING **: cannot open display: :0.0


Einloggen kann ich mich als root aber ganz normal:
pascal@debian:~ $ ssh root@localhost
[...]
root@debian:~ # echo $DISPLAY
:0.0

Müsste da ":10.0" stehen?

Meine /etc/ssh/sshd_config hängt dran und in der /etc/ssh/ssh_config
steht folgendes:
Host localhost
    ForwardAgent yes
    ForwardX11 yes


Bitte helft mir auf die Sprünge, ich weiss nicht wo noch suchen kann.

TIA,
Pascal
